The single-mission counterpart to the StealthBasedGame, where the player must sneak through an area infested with enemies. Getting detected may result in automatic failure and/or death or just mean being besieged by lots of guards. Being thrown in an [[CardboardPrison easily escapable jail cell]] is also common. Frequently means dealing with [[TheGuardsMustBeCrazy guards that have no sense of peripheral vision]] (or even hearing), so the player may only have to avoid direct line of sight with them to slip past.

Sometimes combined with a SnipingMission. Otherwise often occurs after [[NoGearLevel the player has been stripped of their weapons]]. If there are alternatives to complete the mission and stealth is only an option, it's OptionalStealth.

See also StalkingMission, which also involves stealth but for different reasons.

[[folder: Action Adventure]]
* Ever since ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', the series have had at least one:
** ''Ocarina'' has Hyrule Castle, where you have to avoid the guards standing outside then sneak around the patrolling guards inside, and the Gerudo Fortress, where you have to avoid being thrown in jail. There's also the Gerudo Fortress mission, which [[DownplayedTrope downplays]] the mandatory nature of these missions: Since your captors [[TheGuardsMustBeCrazy didn't notice that you're carrying a trunkload of weaponry]], getting back out of your cell and simply neutralizing the guards is a snap.
** ''VideoGame/TheLegendOfZeldaMajorasMask'' has the Deku Palace and Pirate's Fortress, made laughably easy if one uses the Stone Mask. Although, in places where you were forced to fight, the pirates would always point out that the mask doesn't fool them.
** ''VideoGame/TheLegendOfZeldaOracleGames'':
*** ''Oracle of Ages'' does it in Ambi's Castle -- you have to dodge guards outside and inside. Unusually, once you get inside, if you get caught you don't get immediately thrown out - the guards just attack you, but if not defeated fast, they will call out to other guards who ''will'' throw you out.
*** In ''Oracle of Seasons'', you have to follow a Subrosian to a hidden portal without being seen by hiding behind trees. Alater trip to Subrosia has two guys steal your equipment, forcing you to get it back.
** ''VideoGame/TheLegendOfZeldaTheWindWaker'' has the Forsaken Fortress, in which you lose your sword and are forced to avoid being spotted by the enemies. Unlike earlier examples, there aren't any ways to simply bypass dealing with sentries altogether, but you can hide in a barrel [[MobileShrubbery the same way Snake hides in a box]] to get around them.
** ''VideoGame/TheLegendOfZeldaFourSwordsAdventures'' had a few stages where you had to avoid the spotlights that searched the area.
** Played straight and downplayed in ''VideoGame/TheLegendOfZeldaTwilightPrincess'':
*** In both Old Kakariko and the Arbiter's Grounds bulblin camp, since there's virtually no penalties for being spotted (aside from getting shot at and rushed), they tend to play out more as [[TheWestern a western shoot-out]] and TheWarSequence, respectively. Also, nighttime makes it harder for them to see you.
*** Two moments that involve Wolf Link: In both, you're stuck as the lupine form and you have to get past a bar filled with people via tightropes and catwalks without falling or breaking/knocking down the many, many pots up there. Failure means being knocked out of the bar and you have to start all over again. There's also Ordon, again as Wolf Link, where if Rusl sees you he attacks you with a torch (though he doesn't move fast due to his injury).
** ''VideoGame/TheLegendOfZeldaPhantomHourglass'' has the Temple of the Ocean King, which is basically half the game. [[ExpositionFairy Ciela]] even sums the trope up nicely: "So we have to sneak around here like thieves!?"
** ''VideoGame/TheLegendOfZeldaSpiritTracks'' has quite a few too, but added the ability to have one character distract a guard while the other character sneaks around. For example, early in the game you have to sneak Zelda out; the player can walk around and be seen as much as he wants - it's ''Zelda'' who needs to be stealthy.
** ''VideoGame/TheLegendOfZeldaSkywardSword'' has the [[spoiler: third trip]] to Eldin Volcano. It's a combination of the ''The Wind Waker'' example and the concept of the stolen gear scenario seen at one point in ''Oracle of Ages''.
*** The Silent Realm segments also count, as they play similarly to the ones in ''Phantom Hourglass'' - gather [[MacGuffin MacGuffins]] and avoid invincible enemies. Getting a MacGuffin puts the Guardians into a sleep mode for 90 seconds, and if you're quick enough you can grab all of them without letting the timer end, but you have to avoid spotlight enemies that will wake them up if they spot you while doing it.
** ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' has the Dark Palace's surrounding area, where you must sneak past cultists to reach the Dark Palace itself. Thankfully, there's a [[SavePoint Weather]] [[WarpWhistle Vane]] at the palace entrance, after you've passed the guards.
* On the subject of Zelda games, ''VideoGame/StarFoxAdventures'' is more in the style of ''Zelda'' games... and guess what? You have to sneak around the prison in Cloudrunner Fortress until you can disguise yourself as a [=SharpClaw=] and get Krystal's staff back.
** Or just run though and don't step in any of the three small puddles.
* In ''VideoGame/{{Metroid}} [[TheRemake Zero Mission]]'', after finishing what used to be the "[[VideoGameRemake original game]]", Samus flees to her ship and takes off her armor. Uh, bad idea. She gets shot down by SpacePirates, resulting in her being without a ship... ''or'' her armor. You then have to slink around a Space Pirate base as ordinary, no PoweredArmor Samus, armed with only a stun gun. Avoiding conflict is ''highly'' recommended. (Of course, once ''VideoGame/SuperSmashBros Brawl'' rolled around, it made Zero Suit Samus into a combat BadAss like her "regular" self, and made her stun gun into a [[WhipItGood laser whip]].)
* ''VideoGame/{{Fahrenheit}}'' (released as ''Indigo Prophecy'' [[MarketBasedTitle in the US]]) has several stealth missions taking place in {{flashback}}s to the protagonist's childhood (he lived on a military base and apparently enjoyed sneaking into places the guards wouldn't want him to be). These are generally considered to be [[ScrappyLevel Scrappy Levels]].
* The ''VideoGame/HarryPotter'' games have a number of missions in which you wander around under an invisibility cloak, and one mission where you have to avoid being seen ''without'' an invisibility cloak (because the potion that turned you into a Slytherin wears off before you get out of the Slytherin-only part of Hogwarts).
** Some hilarity can ensue if you deliberately get yourself caught by a non-Slytherin prefect while the potion's still working [[TakeYourTime (which, since it's a plot point, is pretty much indefinitely)]]. [[TheDevTeamThinksOfEverything The game will take points away from Slytherin instead of Gryffindor like they usually do.]]
* Retrieving the Green Hive in ''VideoGame/{{Overlord}} II'' requires the Overlord to possess a Green Minion and lead a group of them into an Empire base. He and his minions then have to sneak around and BackStab the forces guarding the base, including the magic detecting Sentinels and the Eradicators, which are ExactlyWhatItSaysOnTheTin. This section is pretty forgiving; the Overlord himself can't actually die here (the Minion does, but you can get more) and if you lose a few Minions there are jars with reinforcements scattered about the base. Plus, you get to sic [[BearsAreBadNews Giant Pandas]] on the guards here. One of the more well thought out and entertaining examples of this trope. The mission where you have to rely on the Blue Minions in the sewers isn't so bad either thanks to their ''invisibility'' power. Being invisible makes a StealthBasedMission ''much'' easier.
* ''VideoGame/BatmanArkhamAsylum'' alternates between stealth and action, but a few missions are explicitly stealth-based, since Joker's got hostages and instructs his goons to kill them the second they see Batman, or even think Batman's around; the Joker helpfully informs them, [[GenreSavvy if the goons start vanishing mysteriously, that means Batman is there]].
* There are lots of stealth-based missions in ''SecretAgentBarbie''.
[[/folder]]

[[folder: Action Game]]
* UrExample: In ''[[http://en.wikipedia.org/wiki/005 005]]'', a spy-themed ArcadeGame produced by Creator/{{Sega}} in 1981, one of the game's four "scenes" has the player hiding out in a ContainerMaze while trying to avoid searchlights carried by cops.
* Some stealth segments appear in ''VideoGame/{{Hulk}}'' as Banner.
* ''VideoGame/HotlineMiami'' throws you into a stealth based mission about half way through the game. It's made [[ThatOneLevel even worse]] by the fact that any time you move, your screen starts to grow static-y, glow white, and and an ear-piercing screech starts to fill your sound, and if you walk for more than about eight seconds, your character becomes paralyzed for a few seconds which almost always gets you caught.
[[/folder]]

[[folder: Adventure Game]]
* ''VideoGame/DreamfallTheLongestJourney'' has the Grubber cave, where you must match four symbols to statues while avoiding the Grubbers and fighting the camera.
* ''Videogame/BrokenSword 3'' has some, of the ScrappyLevel variant.
* ''VideoGame/KingsQuestIV'' has Lolotte's castle, in which Rosella must sneak past a handful of (asleep) guards.
* ''VideoGame/GabrielKnight: Sins of the Fathers'' has two variations of the Stealth Based Mission; first, he has to escort a mime from one side of Jackson Square to a police officer on the other side, and avoid all of the other townsfolk along the way (lest they distract the mime). Later, Gabriel has to call [[ScaryBlackMan Dr. John]] out of his chamber, sneak into it while he's out, and avoid being spotted. But Dr. John is the only enemy he has to avoid.
[[/folder]]

[[folder: Beat 'em Up]]
* The ''Film/{{Spider-Man}}'' movie game has two stealth missions, both regarded as [[ScrappyLevel Scrappy Levels]] due to lack of open movement.
** The noir sections of SpiderManShatteredDimensions are largely played in this style, requiring Spider-Man to hide in shadows in order to take down Mooks. The only exceptions are a few ambushes and [[BossBattle parts of the boss battles.]]
[[/folder]]

[[folder: Driving Game]]
* Several missions in the ''{{Driver}}'' series require you to follow a car without getting to close and alerting them.
[[/folder]]

[[folder: First Person Shooter]]
* There is a mission in ''VideoGame/CallOfDutyBlackOps'' where the first half has you sneak a squad towards a facility in RTS-style. Getting caught while in RTS mode immediately gets the entire squad killed; you get an achievement for getting through the stealth-RTS section without getting caught.
** ''VideoGame/CallOfDuty 4: VideoGame/ModernWarfare'' has "All Ghillied Up". Stealth isn't mandatory (except for one or two small sections) but it's strongly encouraged.
** Two areas in the "Hunted" mission" involve stealthing across a farm field to avoid enemy patrols. If you get spotted too early on Veteran, your goose is cooked.
* The stealth portions in ''{{Halo 2}}'' (where you play as the Arbiter) frustated many people as they were much less enjoyable to play, even though they had an interesting plot. One of the only complaints of ''{{Halo 3}}'' is that they got rid of the gameplay shifts, but drop a lot of the Arbiter's plot with it.
** To be fair, the stealth sequences in Halo 2 were very similar to the stealth sequences in the first game. Namely, short and optional. You can go in guns blazing if you want to, and the game doesn't penalize you for it.
** During the nighttime sections of ''Halo3ODST'' the player has the option of running around the city guns blazing (as per the usual ''VideoGame/{{Halo}}'' strategy)... or, using the city map that keeps track of Covenant patrols, avoid nearly every enemy on the way to the next objective. The game doesn't care either way but does increase the number of Covenant near objectives and as the game progresses. The daytime sections are classic Halo gunslinging, though.
** Likewise for Nightfall in ''HaloReach''.
* A mission in ''VideoGame/JediOutcast'' requires Kyle to sneak through an enemy base. Of course, you can try provoke all enemies and kill them before they push various alert buttons, by being at the button and kill all enemies trying to push it.
* One very annoying mission in ''ReturnToCastleWolfenstein'' requires you to remain undetected ''in broad daylight, in an open field''; if you're seen even once and fail to snipe the guard in the split second before he hits the alarm, GameOver. And there's one guard you can't shoot or alert, if the latter happens and the alarm is already destroyed, the mission becomes {{unwinnable}}.
* ''VideoGame/{{XIII}}'', which was based on a comic that was in turn inspired by ''[[Film/TheBourneSeries The Bourne Identity]]'', has several missions that fail automatically if the alarms go off. A guard spotting you is not instant-fail as long as you stop him from getting to an alarm button in time, but then you'll have to remember to drag the body somewhere out of the way in case a patrol comes by later.
* Variation: In ''VideoGame/{{BioShock|1}}'', it is possible to get a Gene Tonic that makes you move stealthier when using the wrench, and deal more damage when you hit an enemy who is unaware of you. It is also possible to get a Tonic that, as long as you stand still, makes you invisible. This combination allows you to, if you wish, play as a Wrench Ninja.
** The [[VideoGame/BioShock2 sequel]] manages, [[RuleOfCool implausibly]], to top that: While the same pair of tonics is available, you're playing a Big Daddy. Turning Delta into ''MrDriller, [[{{Tenchu}} Stealth Asassin]]'' dances between ''scary'' and ''friggin' sweet''.
** Comstock House in ''VideoGame/BioShockInfinite'' has some elements of this. You guide Booker through a dilapidated insane asylum full of semi-catatonic patients wearing masks of the Founding Fathers. Unfortunately, each room full of patients also has one of the Boys of Silence, who basically act as security cameras: if a Boy of Silence spots you, he makes [[HellIsThatNoise a horrible screaming noise]] that causes all the patients to start attacking you violently; if that wasn't bad enough, the Boy also generates a shield that makes the patients resistant to your attacks.
*** The entirety of ''Burial at Sea Episode 2'' can be this if the player so chooses. In this expansion, [[spoiler:Elizabeth]] can sneak up behind enemies and knock them out non-lethally, or use the new crossbow weapon with knockout darts from a distance. If you happen to be playing this on "[[NintendoHard 1998 Mode]]", however, stealth is practically mandatory due to the added condition of being restricted solely to non-lethal attacks. Fittingly, promotional art for this expansion (along with the aforementioned "1998 Mode") pay homage to the classic stealth game ''VideoGame/ThiefTheDarkProject''.
* Every time one plays the Spy class in ''VideoGame/TeamFortress2''.
** Or not at all, depending on whether the Spy in question is invisible or just disguised. If the later, he could waltz right in front of the entire opposing team unless they're all paranoid and Spy Check him ([[ProperlyParanoid which any half-way decent set of players would do out of habit]]).
** It also pays to be stealthy as other classes, since some stage objectives have an InstantWinCondition and it's always good to have the first strike.
* Comes up more than once in ''Call Of Cthulhu: Dark Corners Of The Earth.''
* ''PerfectDark'' has two missions, which, while not stealth entirely, rewards you with dual weapons for not being spotted by the guards.
** ''Perfect Dark Zero'' also has three in the game's first act. In the first mission (not including the ForcedTutorial), you must scan three enforcers with the Audioscope without them spotting you or being alerted by other {{mook}}s. In the fourth mission, you have to stealth kill a guard to obtain his radio and shut down enemy communication, then take out the security camera and use a voice changer to trick them into opening the door for you. From there follows more audioscoping, and dodging patrols, {{insecurity camera}}s, and [[OneHitKill killer]] [[LaserHallway laser traps]]. Then there's Laboratory Rescue, where if any alarms are triggered or you shut off the generator without locking it down, BodyguardBabes with {{Hand Cannon}}s are summoned. A little ways into the level, even if you haven't been detected, the lab floods with DeadlyGas that drains your health, and you must quickly find the valve to turn it off.
* A few missions in ''WaterWarfare'' task you to slink, [[NoGearLevel weaponless,]] past opponents to a point. In one, you just have to make it to the goal. In the second, however, you must take a treasure chest back to your base as well.
* The Ultor HQ levels in ''RedFaction''.
* ''SoldierOfFortune II'' has at least three or four stealth levels. In the first one, being spotted results in an instant NonstandardGameOver.
* In the ''MedalOfHonor: Frontline'' level "Operation Repunzel", if the guard at the front desk is "asleep"(which may be a glitch), you can sneak your way through most of the mansion, if he's awake, your cover will immediately be blown. You pretty much have to blow your cover anyway if you're going for the medal.
** ''MedalOfHonor: Allied Assault'' has at least two stealth levels. In the first, you [[DressingAsTheEnemy dress as a Nazi officer]] and infiltrate a U-Boat facility to destroy the U-529, in the second, you stow away in a truck to sneak into and bomb a tank park. In both cases, stealth is optional, but it is much easier than going in guns blazing.
* Several ''VideoGame/RainbowSix'' missions have you infiltrate a house or building without being spotted, which means you can't kill anyone either. The two stealth missions in ''Rogue Spear'' are [[ThatOneLevel especially infuriating]], and they [[RemixedLevel later become action levels]] that are no less difficult.
* ''TimeSplitters'' 2 has plenty of chances for [[OptionalStealth optional stealth]] throughout the game, but for the first half of the Neo Tokyo level you're required to tail a hacker to gain access to an underground base, the only instance of required stealth in the entire game. It's a pretty tough section with security cameras everywhere that give away your position, and if you mess up once you have no choice but to restart the entire mission, so anyone who's been playing the game like a run & gun up until this point or hasn't played ''MetalGearSolid'' (which has a similar radar to the one used in TimeSplitters) is in for a nasty difficulty spike.
[[/folder]]

[[folder: Hack and Slash]]
* The level before the battle with Cloe Walsh in ''VideoGame/NoMoreHeroes2DesperateStruggle'' is a prison complex which you are instructed to sneak through. [[spoiler:Of course, since you're playing as [[MadeOfIron Travis]] [[BloodKnight Touchdown]], if you're spotted, you're free to simply [[CuttingTheKnot butcher the guards]] and carry on your way.]]
[[/folder]]

[[folder: Mecha Game]]
* Even VideoGame/ArmoredCore is not immune to occasionally indulge in this. The first half of a particular mission in ''Armored Core 3: Silent Line'' requires you to stealth your way through a deep ravine filled with AI helicopters. Getting discovered does not equal instant failure, but you only have two seconds maximum to destroy it before it broadcasts an alarm, which ''does'' fail your mission. Adding to the challenge is the existence of a hidden part within the level, and a bonus part awarded for clearing the sneaking part under a certain time limit (they do not, however, need to be obtained in one go). Thankfully, the helicopters are real pushovers; two small missiles will bring down one, and killing them outright before they spot you is a common tactic.
[[/folder]]

[[folder: Platform Game]]
* ''VideoGame/{{The Hobbit|2003}}'' featured lots of these - and they were the "do it right or it's back to the beginning of the level" sort.
* ''VideoGame/RatchetAndClank'' has many frustrating (more for the sheer idiocy of it than difficulty) forced stealth sections in later levels where you are forced to disguise as a security robot. In this disguise, you cannot attack or jump. Un-disguising in the view of the robots will make them run to press a red button which will trigger the security system, which will almost always kill you.
[[/folder]]

[[folder: Real Time Strategy]]
* In ''VideoGame/CommandAndConquer: Red Alert 3'', the first part of the seventh Soviet mission has you sneak into the Japanese Emperor's palace with a single conscript.
** And a Warbear! Controlled by the allied AI unless you're playing with a friend.
* This is essentially what it's like to play [[YouDirtyRat Twitch the Plague Rat]] in LeagueOfLegends. He is amongst the frailest characters in the game but can do a lot of damage very quickly and does almost always have the element of surprise due to his ability to become invisible for up to 50 seconds at a time. Twitch's role on a team is to roam the map and pick off wounded and occupied targets without endangering himself in the process.
* One of the early campaign missions in {{Achron}} requires you to sneak into an alien base while avoiding random patrols. Fortunately, due to time travel, you can see where the enemies will be and avoid them in the past.
[[/folder]]

[[folder: Role Playing Game]]
* ''VideoGame/TalesOfTheAbyss'' has a mission where you have to sneak your way through a forest without alerting any guards. If you're caught, you have to start the section over. However, if you're caught too many times, the game [[AntiFrustrationFeatures allows you to fight your way through instead]].
* ''VideoGame/TalesOfPhantasia'' has Cress and his buddies sneaking through Alvanista castle to check on the prince. Getting caught sends them back to the balcony, but avoiding guards is as easy as running through while they are outside the screen.
* ''VideoGame/CrisisCore: Final Fantasy VII'' features a stealth sequence where Zack, a SOLDIER 1st Class who's been mowing through entire armies for the bulk of the game, has to sneak into a base controlled by the same {{Mooks}} he's been slaughtering the whole time. Getting caught sends you into a battle with a group of them, which Zack will win in under 30 seconds. One wonders why the stealth sequence was necessary.
** [[CutsceneIncompetence Oddly enough]], Zack, who is pretty much unstoppable by ordinary Mooks, gets ''launched'' out of the base if he's discovered. Fortunately, the only thing you get from successfully being stealthy is [[spoiler: a heap of largely useless treasures]]. No one even seems to care if you fail spectacularly.
** Also at one point you use a sniper rifle to take out a number of robots, when you've taken down larger robots with two hits.
** The original ''VideoGame/FinalFantasyVII'' also contains a short stealth sequence in Shinra HQ, but if you fail often enough you'll just go in guns blazing.
* One early mission of ''VideoGame/FinalFantasyXIIRevenantWings'' tasks you with getting from Point A to Point B with Vaan and Vaan alone. Short of obscene LevelGrinding, the only only way to survive is not to get noticed.
** Surprisingly and [[GuideDangIt somewhat unintuitively]], it's possible to give Vaan boots that prevent him from being immobilized by the enemies' lightning-elemental attacks, use an ability that temporarily increases his movement speed that you should already have at that point and have him just run through the level with any enemies in tow either not being able to get close enough to hit him or not being able to do enough damage to kill him before he gets to the goal.
* One could say that only the first ''VideoGame/{{Boktai}}'' game is a StealthBasedGame. The other three games are more action-oriented, with stealth missions on the side.
* Saul D'Alessio's mission in the ''GuildWars'' Bonus Mission Pack requires you to sneak into the Charr camp, defeat their leaders, and then survive the onslaught of every Charr in the camp.
** Even more obviously, Gwen's mission in the same pack. She's largely defenceless, with only a few skills based around speed and even feigning death with a few safe spots to hide in. Between her and freedom: An entire Charr legion. Gulp.
* The escape from prison in ''VideoGame/ChronoTrigger'' was intended as one of these, but the guards are easy enough to kill that it's easier to do just that.
** The unarmed escape from the Blackbird later in the game is a forced stealth mission, unless you happened to put [[BareFistedMonk bare-handed fighter]] Ayla in your active party before your capture.
* Chapter 10 of ''[[VideoGame/FireEmblemTellius Fire Emblem: Path of Radiance]]'' gives you a very large amount of bonus EXP (Experience points you can freely assign, great for MagikarpPower characters) if you escape without alerting the prison guards, but it's possible to ignore stealth and get a slightly greater amount of combat experience. Due to the game's turnbased nature, one of the GameFAQs walkthoughs has a turn by turn method of finishing it.
* Chapter 8-2 of ''VideoGame/ValkyriaChronicles'' finds [[TheHero Welkin]] and {{A|ctionGirl}}licia trapped in a forest at night with none of the rest of TheSquad around to help them, and [[TheEmpire Imperials]] converging on them in every direction. On top of all that, Alicia sprained her ankle and can only limp. The goal is to get from one corner of the forest to the other while avoiding, or at least stealthily taking out, any soldiers, spotlights, or mortars they come across. Not as bad as most, as on-foot-Welkin (he's usually in a tank) and Alicia are both Scouts and have high mobility (even considering her sprained ankle), but that also means their defense isn't that great. Which isn't usually a problem until you run into Shocktroopers, who wield [[MoreDakka machine guns]].
** Or, you can let a spotlight see Welkin next to one of the shocktroopers while he still has a lot of movement left, and [[HilarityEnsues watch the poor sap get mortared instead.]]
* ''VideoGame/GoldenSun'' has a portion where the party has to sneak through a thieves' base in order to rescue the mayor of a large city. The second game has a similar mission where the party must sneak past tribal guards.
* ''[[VideoGame/{{Boktai}} Lunar Knights]]'' has an enemy known as a Spotter. It has no direct attack and simply hovers around your position while a spinning crosshair and a number float over your head. The number is a timer, and you have to get out of the Spotter's sights and hide somewhere safe until the countdown expires and the Spotters return to sentry duty. They also take inordinate amounts of punishment, and fighting one as an underleveled Lucian is suicidal. Also, every time the reacquire their target, the crosshair countdown ticks down faster. What happens when it runs out? [[BoomHeadshot Take a wild guess.]]
* ''KingdomHearts'':
** ''VideoGame/KingdomHeartsCoded'' also has some in Wonderland (depending on how many times you choose to enter certain rooms) where you must sneak past the Card Soldiers, though the only really thing you need to worry about are the Card Soldiers actually catching up to you which isn't all that hard to avoid (especially if you if have the ability Haste equipped).
* ''VideoGame/WorldOfWarcraft'' features some stealth-based quests, specifically for the Rogue class, as they are required to combat special monsters that can only be defeated via attacks from stealth. Being in stealth is also required for Rogues to disarm traps, something that comes in very handy in certain dungeons. Similarly, while not precisely a mission, stealth allows Rogues and Druids to sneak past many encounters, allowing solo or duo completion of many quests that would otherwise require a larger group. For these reasons, learning to use stealth properly is greatly advised for any Rogue who wants to be taken seriously in the game.
** ''Cataclysm'' offered several high-level, high-difficulty stealth missions for rogues, requiring them to avoid numerous enemy patrols in order to reach and assassinate the most ambitious of the surviving black dragons.
** The first third of the Well of Eternity instance is a pseudo-stealth mission. The central courtyard is being used as a staging area for the demon invasion, and being spotted by the demons will result in near-instant death. Instead, you must use the stealth buff from Illidan to reach and destroy the crystals powering the portals, which will stop the demons from spawning.
* ''VideoGame/TheLordOfTheRingsOnline'' has stealth-based missions for the Burglar class. The Burglar also becomes extremely powerful if attacking in Stealth, and is able to kick off certain ComboAttacks in stealth only.
** The quests in the Shire involving mail or pies are stealth missions available to any class, though you don't have to avoid ''everybody'', only specific types of hobbits (Nosy or Hungry, respectively). Some of these missions more frustrating than others (Hungry and Nosy hobbits often tend to loiter near choke points like bridges and passes, and the missions are timed so you can't usually just wait for them to move on).
** The "Chicken" quests (also starting in the Shire) aren't pure stealth missions, but since you're a ''chicken'' with only a few HP, your only real options for passing hostiles are to avoid being noticed or to run and hope you're faster than they are. On the longer chicken runs, it gets worse, since you can probably survive ''one'' hit from things in starting areas (i.e., most of the Shire) but once you get outside that if anything even touches you you're dead.
* ''LostOdyssey'' features your party getting captured. After memory-wiping the guard and convincing him to let you out of your cell, you must sneak around the enemy CoolShip until you find your weapons and can fight back. Getting caught gets you thrown back into the cell, from which the amnesiac guard will dutifully let you out every time.
* ''VampireBloodlines'' - the Prince orders you to investigate the submarine and the museum unseen and without casualties. Stealth is an option on other missions, but no more or less than brute force.
** Inversion when playing as a Nosferatu; stealth is required ''between'' missions, and the game justifiably penalizes you for letting your character be detected.
* ''VideoGame/{{Dubloon}}'' has a short sequence where Riley and Ricky have to sneak past the lowliest mooks in Navy base. Getting caught sends player back to the start, but after a plot event, they can be fought for cheap experience.
* The beginning of ''VideoGame/MassEffect2'''s "Arrival" {{DLC}} is one of these. Or, at least, supposed to be. There's no benefit to sneaking through the prison (there's an achievement for getting through it undetected, but that's it); all of the groups of enemies are so easy to kill that it doesn't particularly matter.
** Before the DLC was released, players speculated that the Infiltrator player class (whose special power is an InvisibilityCloak) would have an unfair advantage, but it doesn't for two reasons: first, the enemies are so easy to sneak past that there's no advantage to using Tactical Cloak anyway; second, even if you do try to sneak past enemies using it, if you enter the area in which enemies would detect you uncloaked, they will automatically attack Shepard once the cloak wears off, [[TheComputerIsACheatingBastard even if there's no possible way for them to know you're there.]]
* In a similar vein, ''VideoGame/DragonAgeII'''s "Mark of the Assassin" {{DLC}} contains an extended stealth-based mission that involves sneaking through a mansion, but it's very merciful if you fail (only sending you back a short distance...with whatever goodies you swiped on your way!) It's also entirely [[OptionalStealth optional]] - fighting your way in gets more random loot and XP, being stealthy nets an Achievement and a few specific goodies.
* At least three instances in ''VideoGame/RuneScape'', all during quests. During Mad Eadgar's Ruse the player must sneak through a heavily guarded storeroom that has the last (until the next quest in the series) supply of the trolls' favourite seasoning herb, getting sent back to the storeroom entrance if caught. In [[spoiler:Branches of Darkmeyer]] the player has to [[spoiler:sneak through the lowest part of the vampyre town in order to find the pieces of clothing they need to disguise themselves as a vampyre, without being caught by the residents or guards who will teleport them back to the entrance.]] And, finally, during [[spoiler:Ritual of the Mahjarrat, the player has to sneak around the plateau where the titular ritual will take place, planting the beacons and heart needed to give their side the edge in the oncoming fight, while avoiding the sniffer beasts that will summon an unavoidable mage who will teleport players to an easily escaped cell.]]
* Ziggy does this in VideoGame/{{Xenosaga}} initially planning to infiltrate MOMO out using a stealth device but it breaks. The game uses line of sight for all enemies so it doesn't really matter if you sneak past the guards or beat everybody up.

[[folder: Simulation Game]]
* ''VideoGame/AceCombat'' shows that you can have "stealth" in flight action titles; ''[[VideoGame/AceCombat3Electrosphere 3]]'', ''[[VideoGame/AceCombat5TheUnsungWar 5]]'', ''[[VideoGame/AceCombat6FiresOfLiberation 6]]'' and ''[[VideoGame/AceCombatXSkiesOfDeception X]]'' have missions where you have to either fly a plane below a certain altitude, avoid circles on the EnemyDetectingRadar representing radar coverage, or both. Getting your style cramped like that naturally makes for [[ThatOneLevel annoying levels]]. The radar circles in ''5'' however, decrease in radius the lower your altitude is, so it does encourage something resembling real-life stealth tactics.
** ''[[VideoGame/AceCombat2 2]]'' manages a mission like this that is completely pointless - you're told to stay below a certain altitude to make a sneak-attack on an enemy base, but you can go above that altitude at the very start of the mission, and the only difference made is when the music switches from downbeat to action mode. The reward for doing it the stealthy way however, are two grounded bomber planes that failed to take off due to your stealthy approach, which, if destroyed, unlocks an optional mission right afterwards.
** ''VideoGame/AceCombatAssaultHorizon'' has a stealth mission on the first half of a Bomber mission when you play Janice Rehl. Not only the radars are placed in very awkward positioning, it is mandatory for you to do so even when you select the already stealthy B-2 bomber.
* ''StarWars Rogue Leader: RogueSquadron II'' has the "Imperial Academy Heist" stage, or, rather, the first 1/3 of it. You have to sneak into an Imperial base by flying low through a canyon. The catch is, you also have to disable a bunch of sensors with your ion cannons[[note]]or avoid them altogether, your only option if you're playing between real-time 6 PM and 6 AM and thus are playing the night version, in which you use the Snowspeeder[[/note]]; flying too high or flying too close to an active sensor results in a GameOver. Destroying the sensors also results in mission failure.
** The first ''RogueSquadron'' had the same canyon at the beginning of the Imperial Construction Yards mission. Only this time, you could destroy the sensors.
* Some missions in ''VideoGame/{{Vietcong}}'' require the player to sneak through an enemy base[=/=]camp. Getting detected just once will instantly fail the mission. This can be problematic if you're not equipped with a silenced pistol, which itself is useless against long range targets. At least the missions in ''Fist Alpha'' are a hell lot easier with the addition of the silenced Sten SMG.

[[folder: Survival Horror]]
* ''VideoGame/ResidentEvil6'' pulls a few of these:
** The most notable segment is Chapter 2 of Jake's campaign, where you are trapped in an underground mine, and are forced to find a way out while the [[ImplacableMan Ustanak]] sends out several insect-like creatures to find you. They function through direct line-of-sight, and if they ever spot you, they will trigger an alarm and you will have only ''seconds'' to find a good hiding spot before the Ustanak arrives. If the Ustanak finds you, it will [[ImpaledWithExtremePrejudice kill you instantly]]. Gunshots will also alert the Ustanak, so you'll be forced to kill any of the bugs that are in your way (read: most of them) from behind using melee attacks. It's one of the few sequences in the game that completely succeeds in being suspenseful and scary, especially for the player who happens to [[TotalPartyKill hide in the same dumpster three times]].
** Also Chapter 3 of Jake's campaign, for the three players out there who were dumb enough to play as Sherry. Since she's weaponless, she has to run and hide from enemies. It's also a CallBack to her DamselScrappy status from VideoGame/ResidentEvil2.
** Chapter 1 of [[spoiler:Ada's]] campaign puts you in a submarine being patrolled by enemies. Getting spotted even once gets you [[ZergRush spammed]] by an endless stream of J'avo.

[[folder: Third Person Shooter]]
* About half the missions in the ''SyphonFilter'' series. In Rhoemer's Base, unlike most, getting spotted doesn't cause an immediate GameOver, but puts the base guards on full alert, making your task much harder. Another "stealth not explicitly required" mission is the Aljir Prison Escape level, if you alert the guards in the last part, Gregorov will most likely be killed, causing mission failure. In ''Omega Strain'''s first Yemen mission, you are disguised as a civilian and must keep your weapon holstered to avoid blowing your cover, also, one of the optional objectives requires that you [[SnipingMission stealth-snipe]] a certain terrorist.

[[folder: Turn-Based Strategy]]
* The PSP TurnBasedStrategy release ''{{Wild ARMs XF}}'' has obligatory stealth sequences. Fortunately, the game establishes the guards' logic instead of forcing you to trial-and-error it (I'm looking at you, ''VideoGame/TheLegendOfZeldaTheWindWaker''), graphically highlights whichever hex tiles the guards are currently observing (I'm looking at you, ''IndigoProphecy''), and ''knows'' you might have to fall back on trial-and-error, and makes that easy.

[[folder: Turn-Based Tactics]]
* In ''Videogame/JaggedAlliance'', some maps have special triggers that activate if the player's mercenaries are detected. For example, when assaulting the military prison in Alma, being detected will send an enemy soldier running to a switch that will flood the cells with mustard gas, killing any of your mercenaries who are being held prisoner there. Another prison allows the mercs to turn this back on the guards; by first talking with a civilian in a shack outside the prison (which itself involves sneaking undetected onto the prison grounds) a key and instructions to activate a tear gas system within the prison can be found. By then sneaking into the office of the Warden, the mercs can trigger a gas release that will knock out every guard inside the prison. If they're detected, the alarm will sound and all the guards will equip gas masks. The game also has plenty of options for "stealthy" play, with characters who have the ability to sneak around, silenced weapons, night-vision gear, and a mechanic to silently kill guards with throwing knives. Because of the open and freeform nature of the game, nearly any battle can be turned into a stealth operation with the right mercenaries and preparation.

[[folder: Wide Open Sandbox]]
* ''VideoGame/GrandTheftAutoSanAndreas'' has a couple of these. [[ScrappyLevel Scrappiness]] is averted somewhat by how [[RuleOfFun fun]] the throat-slitting BackStab attack is.
* In ''VideoGame/TheGodfather: The Game'' and its sequel, there are some of these. Getting spotted usually doesn't instant-fail you, though, but instead forces you to kill the offending guard within a time limit. They are actually rather forgiving and fun.
* Several missions in ''TrueCrime: Streets of L.A.'' involves sneaking and knocking down guards you pass by. Being spotted for too long results a mission failure.
** {{Lampshaded}} by Nick Kang: "Gotta do this... ninja style!" Stealth missions are fortunately brief enough to stay fun, and always end in alerting ''every'' Mook in the place, making a wild shootout necessary anyway...
* Pretty much the entirety of the ''VideoGame/FalloutNewVegas'' DLC ''Dead Money'', which will often actively penalize you if you run around willy nilly and fight any enemy you want. [[spoiler:Late in the DLC, after Dog/God betrays you, you ''have'' to use stealth to disable his traps or else he will immediately subject you to a gruesome NonStandardGameOver.]]
** ''VideoGame/{{Fallout 3}}'' has this for the first leg of the ''Operation: Anchorage'' simulation, where you must sneak up the cliffs and take the Chinese guards out with [[WithThisHerring a rather weak silenced pistol]].
* Despite ostensibly being a StealthBasedGame, ''VideoGame/AssassinsCreedI'' is essentially an action-adventure game with light stealth elements which are enforced only in a handful of missions. These missions are often the most frustrating in the game, as as soon as a single guard sees you (which can happen in under a second if e.g. they turn around when you're moving in for the kill) you're booted back to the last checkpoint after a lengthy loading screen.
** One of the worst abuses of the trope comes in the form of the ''Bonfire of the Vanities'' DLC for ''VideoGame/AssassinsCreedII'', which consists of ''nine'' such missions where the aim is to assassinate targets who are generally surrounded by several guards at all times, with even more at most angles of approach. If you don't get the 'trick' for each one, it's an incredibly frustrating waste of time that takes all the wind out of the sails of the game's finale.

[[folder: Other]]
* In ''{{Yu-Gi-Oh 5D}}s: Stardust Accelerator: World Championship 2009'', you get your Deck and Ruel Runner confiscated, requiring some stealth to get back. Thanks to your security guard disguise, getting caught just gets you sent back to the central room, but it can still be quite annoying to figure out when they can or can not see you, especially since one of the things you have to do is get past a hall of guards to unlock a door in another part of the building for a few minutes, requiring you to traverse two sets of guards within a time limit without being caught.
